  • If the set of rules in that style is expected to grow (i.e. more cards and products), you may wish to look at decision tables or templates, to avoid writing separate rules yourself. However, the way you have written that rule is pretty much valid, although you would need to have an "insertLogical(s)" to put the response object into working memory for retrieval or use in other rules. I think you might need to provide a bit more information about what you're trying to do. – Steve Nov 27 '13 at 08:57
  • Prod_of_Interest ==SBI Platinum Card == "SBI Gold & More Card" there are and && or and || between then? – Narkha Nov 29 '13 at 11:11

Caution: A cascaded if is not equivalent to a set of rules reflecting those conditions. Rules will match and fire independently unless countermeasures are being taken.

This is not really an answer - please follow Steve's advice and provide more information.
